Send Verified checks every address on your list against eight signals — syntax, domain, mail server, mailbox, catch-all, disposable, role and spam traps — and tells you plainly which ones are safe to send to.
No scores to decode. Send to the green pile, think about the amber one, and drop the red.
The mailbox exists and accepts mail.
Real, but may not reach a person — or not for long.
Will bounce, or will hurt your sender reputation.
The server wouldn’t answer clearly. You’re never charged for these.
Drop in a CSV with any columns, a TXT file, or paste addresses straight in. We find the email column and keep the rest intact.
Syntax, domain, mail servers and a live mailbox handshake — no email is ever sent — plus catch-all, disposable, role and spam-trap detection.
Just the deliverable rows, deliverable plus risky, or everything with a result column — as CSV, XLSX or TXT.
Upload lists of up to a million rows. Each address is checked once however often it appears, and every other column is kept.
Stop bad addresses at the form. A quick check answers in well under a second; a full mailbox check in a few seconds, with a score you can act on.
Keep only deliverable rows, add the risky ones, or take everything with a result column — as CSV, XLSX or TXT.
Know which addresses look fine but won’t reach a person — and which look set up to catch you, like misspelt gmial.com domains.
Unknown results go straight back to your balance. Every charge and refund is in your history.
Files and results are deleted 90 days after a task finishes. Two-step sign-in is available on every account.
Check addresses at sign-up, before they reach your database. Quick mode answers from DNS and recent results; power mode adds a full mailbox handshake.
One credit checks one address. Unknown results are always refunded.
A fresh allowance every day. Best for steady sign-up flows.
2,000 to 25,000 credits a day · from $0.20 per 1,000
Pay once, use whenever. Best for big or occasional lists.
50,000 to 1,000,000 credits · 1M for $400
No. When a server won’t give a definite answer, the credit returns to your balance automatically when the task finishes — straight away for a single check.
Verification confirms the mailbox exists right now. Mail can still bounce if your SPF, DKIM or DMARC records are misaligned, your sending IP is blocklisted, or the recipient’s server is temporarily refusing mail.
Daily credits refill every day on a monthly subscription — ideal for steady sign-up traffic. Instant credits are a one-off purchase that never expires. If you have both, daily credits are always used first.
CSV and TXT files up to 50 MB or 1,000,000 rows. CSVs can have any number of columns; we detect the email column and keep the rest in your download.
Uploaded files and their results are deleted 90 days after a task finishes. Single-check history is kept for 90 days as well.
No. We ask the receiving mail server whether it would accept mail for the address and hang up before anything is sent. Nobody on your list hears from us.
